Smoke detector



Designed to detect the first signs of fire (smoke) at the guarded object and transmit the “Fire” signal to the controller.


  • registration in the Security Hub controller after installing the battery using Setup Wizard in the mobile application;
  • two batteries (primary and backup), frame sizes CR123, 3V are included;
  • battery life up to 5 years;
  • battery discharge control;
  • testing the sensor with a laser remote control Astra-942 (purchased separately);
  • sensor tamper detection;
  • removable protective cover included.


Works as part of the GSM Security Hub alarm system for continuous monitoring of the onset of an apartment (house) fire. It allows to quickly respond to the appearance of smoke and eliminate its cause even before a fire occurs.

Operating principle

The sensor constantly monitors the volume of the security zone. The principle of operation of the sensor is based on the detection by the photodetector of infrared radiation that occurs in a smoke chamber in the presence of smoke particles in the air. The sensor analyzes the density of the smoke and generates an alarm message that is sent to the Security Hub controller. A fire message is displayed in the user's mobile application.
